If you would like to know the volume of the cube, you can calculate this using the following steps:
volume = length * width * height
volume = 1 * 1 * 1
volume = 1
The volume of a cube is 1.
B is definatly the correct answer, Add all of the prices, and that is what it costs per sweatshirt
We have to use the function A(t)= a(1 +/- r)^t
So A is going to be the answer- the area after 8 years. t is going to be 8, because t is time. a is 2400 because that's the starting value. Finally, we're going to turn 5.75% into it's decimal form of .0575. That's going to be r, and because the area is decreasing, we will subtract r from 1.
Our new function is:
A=2400(1-.0575)^8
Simplify a little bit.
A=2400(.9425)^8
Bring .9425 to to power of 8 and then multiply by 2400 because PEDMAS.
A=1494.38366866
The rounded answer is 1494 kilometers squared.
I think 6,1 and the upper point is -6,11
Answer:
a) x = 7.5
b) x = 1
Step-by-step explanation:
a)
- (4x - 1)/2 = x + 7
- 4x - 1 = 2(x + 7)
- 4x - 1 = 2x + 14
- 2x = 15
- x = 15/2 or 7.5
b)
- 3x + 2 = (2x +13)/3
- 3(3x + 2) = 2x + 13
- 9x + 6 = 2x +13
- 7x = 7
- x = 1
